Currently, after drawing a seating aisle path, the only way to edit it is in a mode which hides everything else. This makes editing a drawn path near-impossible, and it is often easier to just delete the path and draw it again, since one is often drawing around existing objects in the drawing.
The aisle tool should allow edits to the drawn path that do not hide everything else. Even better, there need not be a separate mode for editing them - it would be fewer clicks if, like many other objects, selecting them would bring up resize handles. Same for seating sections.
